ClientOld was the one from the small autopatch download rar, the one which is now downloading the whole shebang again, at least it goes reasonably fast at ~ 1.5MB/s
I am quite tempted by server where you have hidden features on maps, ideally I'd like to see 'lovingly crafted' euro mir maps with added features like little bonuses, secret places and such likes, that all servers more or less gloss over. Always when I find a door that doesn't work I am disappointed, same when you don't have mass dropping mobs starting with cats, scarecrows etc., when low caves don't hum lively with mobs (same with outdoor maps), disappointed when there's no FT or GK in Mongchon etc.
Edit: Autopatch finished downloading and 'quit', now when I run either client.exe or clientold.exe, autopach briefly downloads Map/0.map and quits, normally stays open and you can click the Launch button.
